Still not as bad as an insight lmao. You can probally call the place that your getting your rental from and change and gm will still foot the bill. When my HHR was in the shop, I got a 4x4 silverado, gas sucked lol. I think they just gave me the most expensive POS off the rental lot lmao.
Been there done that, dealership had my car for an extra day to do the charge piping recall, didnt even do the damn thing even though it was on the list of work performed. Have not had time to let them try to fix it yet.
